The trek to the Rust-Flats was a descent into a landscape that shouldn't exist. If the Low-Grid was the city's sewer, the Rust-Flats were its scrapyard—a vast, hollowed-out cavern where the structural supports of Oakhaven met the tectonic plates of the old world.
Marcus walked at the rear of the scavenging party. There were twelve of them in total, led by Vane. They were a motley crew of "Unranked" survivors, men and women whose bodies bore the scars of industrial accidents and mana-burns.
They moved with a practiced, silent synchronization, their boots wrapped in thick rags to dampen the sound of footsteps against the metal floor.
Kael walked beside Marcus, his heavy toolkit clanking softly. He kept casting worried glances at his friend. Marcus hadn't spoken since they left the Echo. He was in a state of "Active Meditation," his eyes half-closed, his mind focused entirely on the black threads of mana circulating through his limbs.
"The air is getting heavy," Kael whispered, wiping grease from his forehead. "We're close to the ventilation overflow. The Iron-Hides love the heat."
"Focus on your breathing, Kael," Marcus said, his voice sounding hollow. "The space is starting to curve."
They emerged into a chamber so vast that Vane's tactical lights couldn't reach the ceiling. Instead, the space was illuminated by the "Eternal Glow" of oxidized mana-pipes—a dull, throbbing orange that made the entire cavern look like the inside of a dying furnace.
Spread out across the floor were the remains of ancient transport ships and construction cranes, twisted into jagged mountains of rust. And moving among them were the Iron-Hides.
They were massive, six-legged reptilian creatures, their scales made of high-density carbon-steel scavenged from the ruins. They didn't eat meat; they ate metal, grinding down the ancient girders with jaws that could snap a ceramic support beam.
Their presence was a vital part of the Low-Grid's ecosystem—they "cleaned" the ruins, but they were territorial and incredibly lethal.
"Form the perimeter!" Vane commanded in a harsh whisper. "Kill-team to the front. Scavengers, get the harpoons ready. We don't take the big ones. Target the juveniles on the edges."
Marcus stepped forward, unsheathing the scrap-saber. He didn't join the harpoon team. He stood twenty paces to the left, his feet planted firmly in the rust-dust.
"What is he doing?" one of the scavengers hissed. "He's going to draw the whole pack!"
"Let him," Vane said, her eyes fixed on Marcus. "Let's see if the Shadow-boy learned anything from his bruises."
A juvenile Iron-Hide, the size of a small car, detached itself from a rusted crane and hissed. Its eyes were glowing red sensors, and its metallic scales rattled with a sound like a thousand knives clashing. It sensed the "Void" in Marcus—a hunger that rivaled its own.
It charged.
The ground shook under its weight. In the past, Marcus would have panicked. He would have summoned a massive, clumsy spike of darkness that would have drained his tank in seconds.
But as the beast bore down on him, Marcus remembered Elara's words. Feel the weight.
He didn't move until the Iron-Hide was ten feet away. He didn't jump. He simply "tilted" his perception. He pushed a thread of shadow into the air in front of him, not to create a physical barrier, but to thin the space.
The Iron-Hide, expecting the resistance of air, suddenly hit a "vacuum pocket." Its front legs buckled as the physics of its charge were momentarily deleted. It stumbled, its massive head dipping toward the dust.
Marcus moved. He didn't swing the sword with his arms; he let the shadow-coils around the hilt pull the blade through the air.
[Technique Unlocked: Ghost-Strike — First Iteration]
The scrap-saber moved in a silent, blurred arc. Because the shadow had swallowed the friction, the blade didn't "hit" the Iron-Hide's neck; it slipped through the gaps in the metal scales like a hot wire through wax.
There was no sound of impact. Only a wet, metallic shink.
The Iron-Hide's head tumbled into the dust, sparks showering from its severed spinal cables. The body skidded another five feet before slamming into a rusted pillar.
Marcus stood still, his breath even. He had used less than 1% of his mana.
"Better," the Shadow Creator whispered. "You are learning to stop being a hammer. You are becoming the cold that makes the metal brittle."
The kill was clean, but the scent of severed cables and leaking hydraulic fluid was an alarm. Deep in the heart of the Flats, an Alpha Iron-Hide—a beast the size of a house—let out a metallic roar that vibrated in Marcus's very teeth.
"The pack is turning!" Vane yelled. "Retreat to the chokepoint! Now!"
The scavengers scrambled, dragging their bags of scrap. But the Iron-Hides were faster. A dozen of them erupted from the rust-mounds, their legs churning the dust into a blinding red cloud.
"Marcus! Run!" Kael screamed, tripping over a piece of rebar.
Marcus looked at Kael. He looked at the wall of metal and teeth rushing toward them. He felt the cold vibration in his neck—the black veins pulsing with an urgent, violet light.
I am the cage, Marcus thought. And the cage is open.
He didn't run. He stepped in front of the fallen Kael and drove his scrap-saber into the ground.
"Stay down!" Marcus roared.
He reached deep into his core. He didn't pull a thread; he pulled the anchor. He forced his shadows to expand not outward, but downward, into the very structure of the Flats.
[Ability Triggered: Shadow-Anchor]
The area around Marcus and Kael—a circle ten feet wide—suddenly turned pitch black. The light of the orange pipes couldn't enter. The sound of the stampede vanished. Inside the circle, gravity seemed to double, pinning Kael to the floor and stabilizing Marcus's stance.
The stampeding Iron-Hides hit the edge of the shadow-circle.
It was like hitting a wall made of absolute nothingness.
The lead creatures didn't crash; they were absorbed. Their momentum was sucked into the void, their massive bodies piling up at the edge of the darkness, unable to penetrate the "Dead-Zone" Marcus had created.
Marcus's face was contorted in agony. His eyes were bleeding violet tears. Holding the "Anchor" was like trying to stop a tidal wave with a sheet of paper. His muscles were tearing, his bones groaning under the pressure of the cosmic experiment.
"You are breaking, 00560," the Creator mocked. "Is this the 'Strength' you worked so hard for? To be a doorstop?"
"I... am... enough!" Marcus screamed.
With a final, desperate heave of his will, he "flipped" the Anchor. Instead of absorbing the momentum, he expelled it.
The shadows exploded outward in a shockwave of dark kinetic energy. The Iron-Hides were thrown back, their metal scales shattering, their heavy bodies tossed like autumn leaves.
The cavern went silent.
The shadow-circle vanished. Marcus collapsed, his scrap-saber snapping in half as it hit the stone. He lay in the dust, his skin so pale it was almost translucent, the black veins on his neck looking like scorched Earth.
Kael scrambled up, his hands shaking as he grabbed Marcus's shoulders. "Marc! Marc, talk to me! You idiot, you nearly turned inside out!"
Vane and the other scavengers approached slowly. They looked at the carnage—at the dozens of broken Iron-Hides and the scorched ground. They didn't look at Marcus as a "Newbie" anymore. They looked at him with a fear that was bordering on reverence.
"He saved us," one of the scavengers whispered.
"He's a monster," another replied.
Vane stood over him, her crossbow lowered. She looked at the broken scrap-saber. "I told you to learn to fight like a human, Marcus. I didn't tell you to try and become a god in a single afternoon."
She knelt down and pressed a damp cloth to his forehead. "You won the hunt. We have enough plating to feed the Echo for three months. But look at your hands."
Marcus looked. His fingernails weren't just black now; they were pointed, hardened into something that resembled the claws of the Shadow Hounds. His skin was cold to the touch—not the cold of a corpse, but the cold of a void.
"You're winning the grind, boy," Vane said, her voice unusually soft. "But you're losing the man. Is she worth it?"
Marcus looked toward the direction of the Echo, where Liora was waiting. He thought of the medicine, the stabilizers, and the golden eyes of Subject 00561.
"Yes," Marcus whispered, his voice a dry rasp.
He tried to stand, but his legs failed. Kael caught him, slinging Marcus's arm over his shoulder.
"I've got you, Marc," Kael said, his voice thick with emotion. "Always."
As the party began the long trek back, the shadows at Marcus's feet didn't follow him. They lingered for a moment, dancing in the dust of the broken Iron-Hides, tasting the lingering energy of the kill.
Deep in the void, the experiment report updated.
